Demux FLAC audio from MKV file?

[fbrdphreak]

This was the best forum I could find to put this in, so here goes:

I've got a couple MKV files which have a FLAC audio stream in them. I'd like to extract (demux) the FLAC audio stream.

"MKV Demux All" doesn't support FLAC. I couldn't get Virtualdubmod, MKVextract or MKVtoolnix to work. I haven't tried eac3to yet.

Anyone done this before? Any tips on how to use Virtualdubmod, MKVextract or MKVtoolnix?

TIA

And as soon as I post this, I figured it out.

Eac3to works like a charm, follow the instructions here: http://en.wikibooks.org/wiki/Eac3to/How_to_Use#Using_container_files_as_input
